You should use string, and 1st make an anchor loop tied around the base of the plant and tied to your pot (by poking a hole through it) and gently bend your plant over to a 90 degree angle and make a loop with the string and tie it to the pot in the opposite direction, after you've topped it. Then you can tie all the other shoots where you want and make a nice even canopy. Then you can top some more if you want and make lots of tops . Great for scrog
